A yoga block in the preferred embodiment is preferably composed of lightweight yet sturdy materials such as: foam, cork, or natural wood, but is in no way limited to these suggested materials.
The device disclosed is an exercise unit which serves as a cushioning device to aid in reducing wrist and hand pain and/or discomfort incurred during exercise done on a floor or other surface, such as yoga and pilates. The exercise unit comprises a main support frame which is approximately equal in size to the hand of an adult. The exercise unit may be roughly described as an essentially square-shaped box, having one open side. A user places the device upon a floor or other surface such that the open side is oriented orthogonally to the floor surface and facing away from the user. This arrangement causes one side of the box, designated as the “upper platform” to be oriented parallel to the surface and designated as the “top” side. The user then places his/her palm on the top side, thus simultaneously allowing insertion of four fingers of the hand into the open side. A layer of cushioning foam is permanently attached to the top side. Users of the exercise unit would normally use two of the devices, one for each hand, during exercise maneuvers.
